func (*Communicator) UploadDir

func (c *Communicator) UploadDir(dst string, src string, exclude []string) error

type Config

type Config struct {
	common.PackerConfig `mapstructure:",squash"`

	ExportPath string `mapstructure:"export_path"`
	Image      string
	Pull       bool
	// contains filtered or unexported fields
}

func NewConfig

func NewConfig(raws ...interface{}) (*Config, []string, error)

type ContainerConfig

type ContainerConfig struct {
	Image   string
	Volumes map[string]string
}

ContainerConfig is the configuration used to start a container.

type DockerDriver

type DockerDriver struct {
	Ui packer.Ui
}

func (*DockerDriver) Export

func (d *DockerDriver) Export(id string, dst io.Writer) error

func (*DockerDriver) Pull

func (d *DockerDriver) Pull(image string) error

func (*DockerDriver) StartContainer

func (d *DockerDriver) StartContainer(config *ContainerConfig) (string, error)

func (*DockerDriver) StopContainer

func (d *DockerDriver) StopContainer(id string) error

func (*DockerDriver) Verify

func (d *DockerDriver) Verify() error

type Driver

type Driver interface {
	// Export exports the container with the given ID to the given writer.
	Export(id string, dst io.Writer) error

	// Pull should pull down the given image.
	Pull(image string) error

	// StartContainer starts a container and returns the ID for that container,
	// along with a potential error.
	StartContainer(*ContainerConfig) (string, error)

	// StopContainer forcibly stops a container.
	StopContainer(id string) error

	// Verify verifies that the driver can run
	Verify() error
}

Driver is the interface that has to be implemented to communicate with Docker. The Driver interface also allows the steps to be tested since a mock driver can be shimmed in.

type ExportArtifact

type ExportArtifact struct {
	// contains filtered or unexported fields
}

ExportArtifact is an Artifact implementation for when a container is exported from docker into a single flat file.

func (*ExportArtifact) BuilderId

func (*ExportArtifact) Files

func (a *ExportArtifact) Files() []string

func (*ExportArtifact) Id

func (*ExportArtifact) Id() string

func (*ExportArtifact) String

func (a *ExportArtifact) String() string

type MockDriver

type MockDriver struct {
	ExportReader io.Reader
	ExportError  error
	PullError    error
	StartID      string
	StartError   error
	StopError    error
	VerifyError  error

	ExportCalled bool
	ExportID     string
	PullCalled   bool
	PullImage    string
	StartCalled  bool
	StartConfig  *ContainerConfig
	StopCalled   bool
	StopID       string
